Description Fei Yang 2017-08-17 01:36:58 UTC 
On joule compute module, soon after doing
# echo freeze > /sys/power/state
the device will crash after it wakes up from suspend.
The kernel version is 4.9.27-intel-pk-standard
The xf86-video-intel version is xf86-video-intel/2_2.99.917
This is the crash dump:
[ 84.844432] [drm] GPU HANG: ecode 9:0:0xfffffffe, reason: Hang on render ring, action: reset
[ 84.853874] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[ 84.864454] [drm] Please file a new bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[ 84.874444] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[ 84.885309] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
